How to show board admin?

Page All boards /jira/boards

For some projects administrator is shown, for some projects it is not. Look at the last line.

What is the reason of hiding admins?

Today there was a post from another user who said they changed the Administrators for a board, and after that it showed black in the View All Boards screen like you are seeing.

I wonder if the same thing has happened in your instance.
